Alias X had been active for a year by the time of his first story. After capturing a criminal he would leave a calling card saying "With compliments, Alias X". He tells his origin to the publisher of the Gazette and the Commissioner. He was a taxi driver in a small mid-west town, but was arrested for being the getaway driver for some murderous bank robbers. After spending two years in jail, he escaped and devoted himself to becoming a master disguise so he could track down the killers. He tells the publisher and the commissioner that the day he captures the killers he'll come clean and reveal his true identity, but until then he can published as Joe Smith for the story.

During the case known as the ''Circus of Death'', Alias X investigates the murder of J.P. Westwell and pursues the stolen rifle plans, ultimately confronting Poppy the Clown. Despite nearly being killed when Poppy cuts his trapeze rope, Alias X recovers in time to help defeat the villain. He shows compassion and respect for Tanga, the Lady of the Snakes, in her final moments by giving her a requested farewell kiss as she dies in his arms.
